Penile fracture in a patient with Ehlers-Danlos syndrome: A case report.

Urol Case Rep

November 2019

The James Buchanan Brady Urological Institute and Department of Urology, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

The association of penile fracture with Ehlers-Danlos syndrome (EDS) has never been described. Our patient is a 41-year-old male with EDS who presented with a traumatic penile fracture, ten days following sexual intercourse. This report recognizes the possible heightened risk of structural penile injury in patients with connective tissue disorders such as EDS and emphasizes a need for a high index of suspicion of occult urethral injury and special considerations in surgical management of these complex cases.

Context: European and North American guidelines recommend Y-chromosome microdeletion (YCM) screening in azoospermic and oligozoospermic men with sperm concentrations of <5 million sperm/ml; however, numerous studies have suggested that YCMs are rare when sperm concentrations are >1 million sperm/ml.

Objective: We systematically reviewed and meta-analyzed European and North American studies to determine the prevalence of a complete YCM in oligozoospermic men with sperm concentrations of >0-1, >1-5, and >5-20 million sperm/ml, and to determine whether 1 or 5 million sperm/ml is the most appropriate sperm concentration threshold for YCM screening.

Recent Updates on Molecular Imaging Reporting and Data Systems (MI-RADS) for Theranostic Radiotracers-Navigating Pitfalls of SSTR- and PSMA-Targeted PET/CT.

J Clin Med

July 2019

Johns Hopkins School of Medicine, The Russell H Morgan Department of Radiology and Radiological Science, Division of Nuclear Medicine and Molecular Imaging, Baltimore, MD 21287, USA.

The theranostic concept represents a paradigmatic example of personalized treatment. It is based on the use of radiolabeled compounds which can be applied for both diagnostic molecular imaging and subsequent treatment, using different radionuclides for labelling. Clinically relevant examples include somatostatin receptor (SSTR)-targeted imaging and therapy for the treatment of neuroendocrine tumors (NET), as well as prostate-specific membrane antigen (PSMA)-targeted imaging and therapy for the treatment of prostate cancer (PC).

Prostate-Specific Membrane Antigen (PSMA)-Targeted PET Imaging of Prostate Cancer: An Update on Important Pitfalls.

Semin Nucl Med

July 2019

The Russell H. Morgan Department of Radiology and Radiological Science, Johns Hopkins University School of Medicine, Baltimore, MD; The James Buchanan Brady Urological Institute and Department of Urology, Johns Hopkins University School of Medicine, Baltimore, MD. Electronic address:

The continuing adoption of prostate specific membrane antigen (PSMA)-targeted PET for prostate cancer molecular imaging requires imagers and clinicians alike to be aware of the increasing number of potential interpretive pitfalls that have been reported. This review summarizes and illustrates the spectrum of benign and malignant nonprostatic conditions with high PSMA-radiotracer uptake that may be mistaken for sites of prostate cancer and also discusses potential false negatives. We discuss the recent literature on the effect of androgen deprivation therapy on lesion detection.

The next era of renal radionuclide imaging: novel PET radiotracers.

Eur J Nucl Med Mol Imaging

August 2019

Department of Nuclear Medicine/Comprehensive Heart Failure Center, University of Wuerzburg, Oberduerrbacher Strasse 6, 97080, Wuerzburg, Germany.

Although single-photon-emitting radiotracers have long been the standard for renal functional molecular imaging, recent years have seen the development of positron emission tomography (PET) agents for this application. We provide an overview of renal radionuclide PET radiotracers, in particular focusing on novel F-labelled and Ga-labelled agents. Several reported PET imaging probes allow assessment of glomerular filtration rate, such as [Ga]ethylenediaminetetraacetic acid ([Ga]EDTA), [Ga]IRDye800-tilmanocept and 2-deoxy-2-[F]fluorosorbitol ([F]FDS)).

Localized prostate cancer rarely undergoes a shift in metabolism towards aerobic glycolysis, a process known as the Warburg Effect. Because of this, positron emission tomography (PET)/CT imaging using 2-deoxy-2-[F]fluoro-d-glucose (F-FDG) is uncommonly used to evaluate patients with early-stage prostate cancer. However, men undergoing an F-FDG PET/CT for unrelated reasons will on occasion be found to have radiotracer uptake within the prostate gland.

Purpose: In this study, we aimed to quantitatively investigate the biodistribution of [F]DCFPyL in patients with prostate cancer (PCa) and to determine whether uptake in normal organs correlates with an increase in tumor burden.

Procedures: Fifty patients who had been imaged with [F]DCFPyL positron emission tomography/computed tomography (PET/CT) were retrospectively included in this study. Forty of 50 (80 %) demonstrated radiotracer uptake on [F]DCFPyL PET/CT compatible with sites of PCa.

Purpose: Prostate-specific membrane antigen (PSMA)-targeted positron emission tomography (PET) imaging has impacted the management of patients with prostate cancer (PCa) in many parts of the world. PSMA-targeted endoradiotherapies are also being increasingly utilized and for these applications, the radiopharmaceutical distribution in normal organs is particularly important because it may limit the dose that can be delivered to tumors. In this study, we measured both interpatient and intrapatient variability of [F]DCFPyL uptake in the most relevant normal organs.
